2. Description of the Related Art In recent years, portable telephones have come to be used not only for telephone calls but also as a portable information terminal having a browser such as the Internet, an electronic mail transmission / reception terminal, and a schedule management function. Therefore, it is desirable that the display contents are various such as a large amount of character information and images, and that the display is large.

Conventionally, in addition to the straight type, the mobile phone has a foldable structure in which the housing is composed of two units and both units are joined by a joining member so as to be foldable in order to meet the demand for miniaturization. A sliding structure in which two units are slidably coupled is used.
Such a structure is extremely suitable because it can secure an arrangement space even when a large-sized display is mounted. In a mobile phone having a folding structure, the display is generally arranged on an inner surface when folded, and is protected from the outside when folded when not in use. It is also known that a sub-display is provided on the back surface or the like so that the minimum amount of information can be displayed even in the folded state.

The slide type structure generally has a main housing (first
(Unit) and a movable housing (second unit) on which a part of the functional parts are mounted so as to be slidable in the longitudinal direction with respect to the main housing, and both units are retracted so that they overlap with each other and carried. When talking, etc., slide both units so that they are separated from each other in the long axis direction and use them. Many mobile phones having a sliding structure are protected by hiding the display unit by sliding both units into a retracted state when not in use.

For example, Japanese Unexamined Patent Publication No. 7-312631 discloses a first housing 1 having at least a receiver and a display,
A portable wireless device provided with a second housing in which a front portion, which is slidably and rotatably attached to the first housing and is housed in the first housing, is provided with an operation unit and a transmitter. Disclosure. By sliding and rotating the second housing, when the second housing is stored in the first housing, a state in which operations and calls can be made,
There are two states: protection with the operating surface inside. The display is protected at the same time as the operation surface.

Further, in Japanese Patent Laid-Open No. 5-91015, a housing provided with a transmitter, a key operation unit, and a display unit, and having a recess extending in the longitudinal direction, and a receiver are slidably incorporated in the recess. A small portable wireless device configured with a movable housing is disclosed. When not in use, the movable housing can be pushed into the recess to reduce the overall size, and the movable housing can be pulled out and used as a desired length. In this small portable wireless device, when the movable housing is pushed into the concave portion to be downsized, a part of the display portion provided on the housing side is exposed to display the time and the like. On the other hand, when the movable housing is pulled out, almost the entire display unit is exposed and more information is displayed. In this state, the distance between the transmitter and the receiver becomes long, so that the call can be favorably performed.

Further, Japanese Patent Laid-Open No. 2001-24762 includes a mobile phone main body having a display unit on one side, and a keypad having an operation button on the surface slidably covering the display unit. There is disclosed a mobile phone in which a part of the display section is exposed from the keypad when the keypad is stored in the main body, and the entire screen of the display section is exposed when the keypad is slid downward. The keypad slides up and down by guide rails provided on both left and right sides of the main body. With this mobile phone, a large display screen can be displayed and a large amount of information such as mail and data can be displayed without impairing portability and operability. In the stored state, the information necessary for voice communication is displayed on the exposed portion of the display unit, and when the keypad is slid to expose the entire screen, character information such as mail can be read or input.

By the way, in the conventional portable telephone having a sliding structure including the above-mentioned example, it is necessary to slide the two portions with both hands to extend the state for voice communication, and there is room for further improvement in usability. Is left.

In addition to the increase in the size of the display device, recently, a mobile phone equipped with an optical function part has been provided to make it multifunctional and highly functional. That is, a mobile phone equipped with an electronic camera for capturing image data is provided.
In addition, a mobile phone equipped with a fingerprint authentication system is provided in order to limit the operation of the mobile phone itself to only authorized users and to confirm the identity of the caller. These optical function parts have an optical opening exposed to the outside,
In order for this optical aperture to function properly, there is a risk that it will not function properly if there is dirt or flaws.

The two units of the substantially plate-shaped movable casing 200 provided with the handset are coupled by a slide mechanism so as to be slidable upward in the longitudinal direction.

FIG. 1 (a) is a side view of the mobile phone 400 in a retracted state (stored state) in which the main casing 100 and the movable casing 200 are stacked, and FIG. 1 (b) is a front view thereof. There is. 2 (a) is a side view of the mobile phone 400 in a stretched state (in use) in which the movable casing 200 is slid upward in the longitudinal direction with respect to the main casing 100, and FIG. 2 (b) is Similarly, the front view is shown. FIG. 3 is a perspective view schematically illustrating an engagement structure between the main housing 100 and the movable housing 200.

The main casing 100 is a unit having almost the same shape as a general mobile phone and having substantially all the configurations and functions of the general mobile phone. However, it does not have a receiver. The handset is provided in a movable housing 200 slidably engaged with the main housing 100, as will be described later.

The main casing 100 has a large display section (LCD display) 101 incorporated in the upper half of the front surface 100f, and the operation section 102 in the lower half of the front surface below the display section.
However, a transmitter section (microphone) 103 is provided near the lower end of the front surface. A touch panel mechanism 107 may be incorporated in the display unit 101. An unlocking operation body (one-touch slide button) 104 is arranged on one side surface of the main housing 100. An antenna 105 is attached to the upper surface of the main housing 100 on the back side. Further, an electric circuit section described later is housed inside the main housing 100.

The central portion of the upper front surface of the main housing 100 is retracted, and the display 101 is arranged slightly back. On the inner side surfaces of the frame-shaped parts 100a, 100a on both sides of the front upper part and on the inner surface of the main housing that follows this, a groove-shaped movable housing for slidably mounting the plate-shaped movable housing 200. A body guide is formed. The edge portion of the main housing 100 corresponding to the lower end portion of the display 101 is formed in a plane shape receding in a semi-arc shape to form a first arc-shaped edge portion 100b.

Movable housing that engages with the main housing 100
The main part of 200 is a flat hollow plate-shaped member, and both side parts are leg-shaped extending parts extending downward. Also, the lower edge of the central portion of the movable casing 200 is formed in a plane shape receding into a semi-arc shape corresponding to the first arcuate edge 100b, and the second arcuate edge 200c is formed.
(See FIG. 3). Therefore, as shown in FIG. 1, when the movable casing 200 is slid downward (reduced state), the movable casing 200 covers and protects most of the upper portion of the display 101, but the second arc-shaped edge portion 200c And the first on the side of the main housing
A substantially circular opening area remains between the arcuate edge portions 100b, and the lower area of the display 101 can be visually recognized from the opening area even from the opening area even if the opening area is in a degenerate state. Only relevant information is displayed. In other words, the mobile phone 400 is configured such that, when the main housing and the movable housing are in a retracted and closed state, the display portion of the main housing is partially stored and protected by the movable housing. Has been done. A handset (speaker) 201 is incorporated in the central portion near the upper end of the front surface of the movable housing 200. The handset 201 is electrically connected to an electric circuit inside the main housing.

It is As shown in the exploded perspective view of FIG.
Guide grooves 100c are formed on the left and right upper portions of the inner surface of the main housing 100. On the other hand, the movable housing 200
Projecting portions 200a extending in the vertical direction are formed on both sides of the back surface of the. At the lower end of this protrusion 200a, a guide rod
200b is installed. By engaging the guide rod-shaped body 200b with the guide groove 100c of the main casing, the movable casing 200 becomes slidable only in the vertical direction with respect to the main casing 100.
In addition, the slide range is specified. It should be noted that when the mobile phone is assembled, the movable housing guide and the protruding portion are invisible from the outside.

The movable casing 200 is constantly urged upward (so that both casings are expanded) by the urging means provided inside the main casing 100. The biasing means is, for example, a coil spring engaged with the lower end of the guide rod-shaped body 200b of the movable housing so as to pull it up. It is preferable that the biasing means be provided with a damping element so that the biasing means can slowly slide. Further, in the retracted state where the movable housing 200 slides downward, the movable housing 200 is resisted against the biasing means.
Is provided with a locking means (lock mechanism).
The locking means is, for example, a locking body that engages in a locking hole provided in the guide rod-shaped body 200b of the movable housing in a retracted state. The locking of the locking means can be released by operating the locking release operating body 104 arranged on one side surface of the main housing 100.

In the embodiment, when the movable casing 200 is slid downward and is in a retracted state (stored state), the lock release operating body 104 provided on the side surface of the main casing is slid to operate the lock releasing operation body 104. The locking means is unlocked, and the movable housing 200 is automatically (one-touch) slid upward with respect to the main housing 100 by the urging means so that the movable housing 200 is in a stretched state (used state) as shown in FIG. Become. In the use state, the transmitter 103 and the receiver 201 are separated by an appropriate distance for a call. Also, the display
The covered part of 101 is exposed, and the entire surface of the display is visible, and the display is in a state suitable for use. The lock release operation body 104 may be configured such that the lock of the lock means is released by pressing the lock release operation body 104.

The mobile phone of the embodiment is provided with expansion detecting means for determining whether the movable casing 200 is in the retracted state in which it is slid downward or in the expanded state in which it is slid upward. . That is, the micro switch is arranged at an appropriate position inside the main housing 100, and when the movable housing is slid downward, a predetermined portion of the movable housing closes the contact of the micro switch. The expansion detection unit determines the slide state based on the contact state of the micro switch.

Next, the electric circuit section and the like of the portable telephone of this embodiment corresponding to the above mechanism will be described. FIG. 4 is a schematic block diagram of an electric circuit section of the mobile phone of the embodiment. Figure 4
As shown in FIG.
RF circuit 106, modem circuit 107, baseband processing circuit
108, codec circuit 109, control unit 110, microphone 103, operation unit (operation key) 102, notification unit 111, display (liquid crystal display: LCD) 101, receiver (speaker) 213, main housing 100 and movable housing 200 And a micro switch 112 for detecting a relative position (extended state) with respect to the touch panel mechanism 113 incorporated in the surface of the display 101.

have.

The RF circuit 106 has a reception circuit, a transmission circuit, and a frequency synthesizer, which are not explicitly shown. The operation keys that make up the operation unit 102 include well-known transmission keys, alphabet / kana / kanji / numeric conversion keys, power on / off
An off key, a cross key for cursor operation, an end key, and the like. The individual portions shown in FIG. 4 which constitute the electric circuit portion of the embodiment may be known ones, and detailed description thereof will be omitted.

The general operation of the mobile phone of the embodiment will be described. The call function and the data transmission / reception function of this mobile phone may be the same as known techniques, and therefore detailed description of the whole will be omitted or simplified, and operations mainly related to the present invention will be described.

First, the operation of the portable telephone when transmitting and receiving a voice signal using the function of the telephone will be described. The antenna 105 receives a signal from the base station and transmits a signal from this mobile phone terminal. The signal from the base station received by the antenna 105 is supplied to the receiving circuit of the RF circuit 106. The receiving circuit selects a signal of a frequency designated by the frequency synthesizer and detects whether the selected signal includes a signal for notifying an incoming call to itself (standby reception).

When the receiving circuit detects a signal for notifying itself of an incoming call, the control unit 110 determines that there is an incoming call.
To notify. Upon receiving the notification from the receiving circuit that there is an incoming call to the own device, the control unit 110 drives the notification means 111 such as a calling bell or a vibrator to notify the user that there is an incoming call to the own device.

In the mobile phone of this embodiment, if the user makes a setting, when the two housings are in a contracted state and an incoming call is made, the user operates the unlocking operation body to move the movable housing. When it slides and spreads and shifts to the use state (communication enabled position), the spread detection unit 116 described above detects this and the incoming / call end control unit 114 automatically goes off-hook, and the telephone line is connected. The voice signal transmitted from the call destination is supplied to the modulation / demodulation circuit 107 via the RF circuit 106. At the same time, the notification control unit 115 stops the notification operation.

The modulation / demodulation circuit 106 demodulates the voice signal transmitted from the call destination, and the baseband processing circuit
Supply to 108. The baseband processing circuit 108 extracts the original baseband signal from the audio signal and supplies it to the codec circuit 109. The codec circuit 109 D / A-converts the supplied baseband signal and then supplies it to the speaker (receiver) 201. This allows the speaker
From 201, the sound transmitted from the call destination is emitted. The codec circuit 109 also performs A / D conversion processing of the audio signal collected by the microphone 103 transmitted from the mobile phone. This allows the user to make a call immediately.

If the above setting is not made, or if the movable casing 200 is already expanded with respect to the main casing 100 at the time of an incoming call, the telephone is called when the user performs an off-hook operation with the call start key. The voice signal transmitted from the call destination when the line is connected is supplied to the modulation / demodulation circuit 205 via the RF circuit 204, and the communication can be performed similarly.

When the call ends, the user can move the movable housing 10
When 0 is slid to the degenerated state, the extension detection unit 116 detects this and the call / end-of-call control unit 114 automatically puts the mobile phone in the on-hook state (end-of-line processing). Of course, when the user performs an off-hook operation with a predetermined end operation key in the expanded state, the call end processing is also performed.

The mobile phone of the embodiment can also send and receive character data and graphics data. The mobile phone monitors whether or not the selected signal includes a signal indicating that character data is transmitted to itself (standby), and the character data and graphics data are transmitted to itself. When it is transmitted to itself, the control unit 208 receives automatically transmitted character data without displaying an off-hook operation, and displays information based on the received data on the display device 101. .

That is, a signal such as character data transmitted from the call destination is supplied to the modulation / demodulation circuit 107 via the RF circuit 106, demodulated, and supplied to the baseband processing circuit 108. The baseband processing circuit 108
Transmitted data such as character data is extracted from the supplied signal and supplied to the control unit 110. The display control unit 117 of the control circuit 110 forms character information and graphics information to be displayed on the display 101 based on the received data supplied from the baseband processing circuit 108, and displays this on the display 101. At the same time, the notification control unit 115 drives the notification means 111 such as a ringing bell or a vibrator differently from the case where a call is made, and notifies the user that character data or graphics data has been transmitted to the user. Notice.

Of course, this mobile phone can prepare message data by itself and send it. Each dial operation key such as 0-9, *, #, etc. provided in the main operation unit 201 is assigned an alphabetic character (alphabet character) or katakana character, and the alphabet / kana / kanji / numeric conversion key is used. I have it. Then, by operating these dial operation key groups and conversion keys,
Enter message data and send it to the other party according to the instruction from the user.

In this mobile phone, when transmitting and receiving character data and graphics data, the display 101 can be used as a horizontally long display to make it easier to see the information displayed. In this case, the display control unit 212 converts the display content according to the horizontally long orientation of the display device and displays it on the display device 101. At this time, the function allocation of the operation keys is changed to correspond to the display orientation as necessary. A sub-operation key that is effective according to this state may be provided on the movable housing side.

In the mobile phone of this embodiment, the upper part of the display 101 is covered and protected by the movable casing 200 in the contracted state, but the lower part of the display 101 is visible. Then, in the standby state, the minimum necessary information when not in use is displayed on the lower visible portion of the display 101. For example, the current time, reception status, remaining battery level, etc. are displayed. Therefore, although no sub-display is provided, effective information can be confirmed even in the degenerated state.

Power may be saved by controlling the display by determining the slide state by the expansion detecting unit. That is,
The display unit is configured to be driven separately, and the slide state is determined by the expansion detection unit so that the display of the unexposed portion is not driven to save power.

In the configuration in which the display unit is illuminated, the illumination function unit is divided and driven, and the display unit 10 in FIG.
When 1 is the contracted state of the slide, the display control unit 117 controls the illumination of the screen portion that is visible from the outside (backlight) and the illumination of the invisible portion is stopped, and that in the stretched state, all screens are illuminated. Control.

Further, the display section is an L-type display using a backlight.
It should be added that not only a CD but also a self-luminous display device such as an EL element may be used. In that case, the display control is
In the contracted state of the slide, only the screen portion visible from the outside is displayed, and the display drive of the invisible portion is stopped.
On the other hand, in the expanded state, so that it can be displayed on all screens,
It is controlled by the display control unit 117. As described above, by configuring the display unit to be driven separately, power saving can be achieved.

In addition to changing the display content, it is possible to perform control according to the slide state. You may change the content displayed at the time of contraction, and the content displayed on the display unit at the time of expansion (at the time of use). That is, the display contents are appropriately switched, such as a rough display in the visible lower part of the display 101 in the contracted state and a detailed display using the entire screen in the expanded state. For example, it is conceivable to move the display of the current time, the reception state, the remaining battery level, etc. to the uppermost part during the expansion (when in use). It should be noted that the change of the display content and the above-described divisional drive of the display can be performed together.

The structure of this embodiment enables the following. That is, since the movable housing can be housed in the main housing equipped with the display, both a large screen and a size reduction can be achieved.
When it is not used, if it is in a degenerated state, most of the display screen is covered and protected by the movable housing. Even in the degenerate state, only a part of the display screen is visible at all times, so that if a minimum amount of information is displayed in this part, it is not necessary to provide a sub display part.

From the stored state, only the sliding operation of the unlocking operation body brings the extended state (used state). That is, the button 1 is not required to pull out the movable housing with both hands.
With one simple operation (one touch), the movable housing can be slid into the operating state, improving usability.

It is possible to detect the slide state and switch the display contents according to the state or switch the function of the operation key (soft key). When an incoming call arrives in the degenerate state, it is expanded only by the sliding operation of the unlocking operation body and the off-hook operation is automatically performed, so that the incoming call can be answered quickly and the usability is improved. To do. When the expanded state is returned to the degenerated state after the call is ended, this is detected and the call ending process is automatically performed, so that the usability is improved.

[Second Embodiment] Next, a second embodiment of the present invention will be described with reference to FIGS. The mobile phone 400C of the present embodiment includes a display unit 101, an operation unit 102, a transmitter unit 103,
And a main housing 100C having a receiver 104, and the main housing 100C
